Definition:	Any member of the class of phosphonic acids in which a carbon atom is directly attached to two phosphonic acid groups. They are analogues of pyrophosphates (with the central oxygen atom replaced by a carbon atom) and like pyrophosphates they tend to have a strong affinity for bone, so are frequently used for their antiresorptive and hypocalcaemic properties.
